Ogosta River
The Ogosta ( bg, Огоста , Latin: ''Augusta''), is the largest river in Northwestern Bulgaria, a right tributary of the Danube. It originates at Chiprovska Mountain, 2,168 meters high section of the Western Balkan Mountains, at about an altitude of 1,760 meters, on the border with Serbia. The towns of Chiprovtsi, Montana, and Miziya are situated on the river's banks. The Ogosta river is 147.4 km in length and is fed by 40 tributaries (including the Skat River) in a watershed of 3,157 square kilometers. The average water discharge in the lower course of the river is 18 cubic meters per second. Along the river's length there are 14 irrigation systems, 8 hydropower plants, and 13 dams. Although the river is used for domestic consumption, it does suffer from pollution, particularly from nitrates. These come from the use of fertilizers that are not fully used by the plants. Other than that, there were intensive mining activities along the river between 1950 and 1999, and facto ...

Danube
The Danube ( ; ) is a river that was once a long-standing frontier of the Roman Empire and today connects 10 European countries, running through their territories or being a border. Originating in Germany, the Danube flows southeast for , passing through or bordering Austria, Slovakia, Hungary, Croatia, Serbia, Romania, Bulgaria, Moldova, and Ukraine before draining into the Black Sea. Its drainage basin extends into nine more countries. The largest cities on the river are Vienna, Budapest, Belgrade and Bratislava, all of which are the capitals of their respective countries; the Danube passes through four capital cities, more than any other river in the world. Five more capital cities lie in the Danube's basin: Bucharest, Sofia, Zagreb, Ljubljana and Sarajevo. The fourth-largest city in its basin is Munich, the capital of Bavaria, standing on the Isar River. The Danube is the second-longest river in Europe, after the Volga in Russia.

Nitrate
Nitrate is a polyatomic ion A polyatomic ion, also known as a molecular ion, is a covalent bonded set of two or more atoms, or of a metal complex, that can be considered to behave as a single unit and that has a net charge that is not zero. The term molecule may or may no ... with the chemical formula . salt (chemistry), Salts containing this ion are called nitrates. Nitrates are common components of fertilizers and explosives. Almost all inorganic nitrates are solubility, soluble in water. An example of an insoluble nitrate is bismuth oxynitrate. Structure The ion is the conjugate acid, conjugate base of nitric acid, consisting of one central nitrogen atom surrounded by three identically bonded oxygen atoms in a trigonal planar arrangement. The nitrate ion carries a formal charge of −1. This charge results from a combination formal charge in which each of the three oxygens carries a − charge, whereas the nitrogen carries a +1 charge, all these adding up to formal c ...

Rivers Of Bulgaria
This is a list of rivers in Bulgaria. The longest river that Bulgaria has a bank on is the Danube (2,888 km), which spans most of the country's northern border. The longest one to run through the country (and also the deepest) is the Maritsa (480 km), while the longest river that runs solely in Bulgaria is the Iskar (368 km). Regions A country rich in water resources, Bulgaria has a large number of rivers that are divided into several regions based on their mouth's location. Rivers of northern Bulgaria, with the exception of the very east of the region, are typically tributaries of the Danube. Notable rivers in the area are the Iskar, Vit, Ogosta, Osam and Yantra. The rivers in the eastern part of the country are typically short (except for Kamchiya) and flow into the Black Sea. Notable rivers in the region include the Kamchiya, Batova, Provadiyska, Devnenska, Ropotamo, Veleka and Rezovska. Most of the rivers that rise in southern Bulgaria have their mouths ...

Ogosta Reservoir
Ogosta ( bg, Язовир Огоста) is a lake and reservoir in the north-west of Bulgaria. The second largest artificial lake in Bulgaria (after the Iskar Reservoir), and also in the wider Balkan Peninsula, it is one of the biggest in Europe. Collecting the waters of the rivers Ogosta, Burzia, and Zlatitsa, the lake begins only 600 meters to the south-west of the edge of Montana city, and its surface is some 60 meters above the ground level of the city. Its water catchment area covers 948 km,2 and the area of the lake itself is 24 hectares. The average water volume is 384 Mm,3 while the maximum volume is 506Mm3. According to the ''Cambridge Ancient History'', the name "Ogosta" may represent the Latin name Augusta.John Bagnall Bury et al., ''The Cambridge Ancient History: the Assyrian Empire'' (Cambridge University Press, 1925, reprinted 1991), p. 595 The construction of the dam which created the lake took twenty years and was completed in 1986.

South Shetland Islands
The South Shetland Islands are a group of Antarctic islands with a total area of . They lie about north of the Antarctic Peninsula, and between southwest of the nearest point of the South Orkney Islands. By the Antarctic Treaty of 1959, the islands' sovereignty is neither recognized nor disputed by the signatories and they are free for use by any signatory for non-military purposes. The islands have been claimed by the United Kingdom since 1908 and as part of the British Antarctic Territory since 1962. They are also claimed by the governments of Chile (since 1940, as part of the Antártica Chilena province) and Argentina (since 1943, as part of Argentine Antarctica, Tierra del Fuego Province). Several countries maintain research stations on the islands. Most of them are situated on King George Island, benefitting from the airfield of the Chilean base Eduardo Frei. There are sixteen research stations in different parts of the islands, with Chilean stations being ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Livingston Island
Livingston Island (Russian name ''Smolensk'', ) is an Antarctic island in the Southern Ocean, part of the South Shetlands Archipelago, a group of Antarctic islands north of the Antarctic Peninsula. It was the first land discovered south of 60° south latitude in 1819, a historic event that marked the end of a centuries-long pursuit of the mythical ''Terra Australis Incognita'' and the beginning of the exploration and utilization of real Antarctica. The name Livingston, although of unknown derivation, has been well established in international usage since the early 1820s. Geography Livingston Island is situated in West Antarctica northwest of Cape Roquemaurel on the Antarctic mainland, south-southeast of Cape Horn in South America, southeast of the Diego Ramírez Islands (the southernmost land of South America), due south of the Falkland Islands, southwest of South Georgia Islands, and from the South Pole.L.

Herder
A herder is a pastoral worker responsible for the care and management of a herd or flock of domestic animals, usually on open pasture. It is particularly associated with nomadic or transhumant management of stock, or with common land grazing. The work is often done either on foot or mounted. Depending on the type of animal being herd, the english language can give different professional names, for example, cowboy for cows, shepherd for sheep, or goatherd for goat. Terminology Herders may be distinguished by sex (''e.g.'', herdsman, herdswoman or herdboy) or by the type of livestock, for example camelherd, cowherd, duckherd, goatherd or shepherd. By country China Tibetan herding communities living in the Tibetan Plateau in the Sichuan Province of southwest China continued to graze herds on common lands even after the 1982 Household responsibility system. Several reasons have been given for the endurance of the traditional pastoral lifestyle: *complex topography preve ...

Hydropower
Hydropower (from el, ὕδωρ, "water"), also known as water power, is the use of falling or fast-running water to Electricity generation, produce electricity or to power machines. This is achieved by energy transformation, converting the Potential energy, gravitational potential or kinetic energy of a water source to produce power. Hydropower is a method of sustainable energy production. Hydropower is now used principally for Hydroelectricity, hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce Carbon dioxide in Earth's atmosphere, carbon dioxide or other Air pollution, atmospheric pollutants and it provides a relatively consistent source of power. Nonetheless, it has economic, sociological, and environmental downsides and requires a sufficiently energetic source of water, such as a river or elevated lake. Int ...

Bulgaria
Bulgaria (; bg, България, Bǎlgariya), officially the Republic of Bulgaria,, ) is a country in Southeast Europe. It is situated on the eastern flank of the Balkans, and is bordered by Romania to the north, Serbia and North Macedonia to the west, Greece and Turkey to the south, and the Black Sea to the east. Bulgaria covers a territory of , and is the sixteenth-largest country in Europe. Sofia is the nation's capital and largest city; other major cities are Plovdiv, Varna and Burgas. One of the earliest societies in the lands of modern-day Bulgaria was the Neolithic Karanovo culture, which dates back to 6,500 BC. In the 6th to 3rd century BC the region was a battleground for ancient Thracians, Persians, Celts and Macedonians; stability came when the Roman Empire conquered the region in AD 45. After the Roman state splintered, tribal invasions in the region resumed. Around the 6th century, these territories were settled by the early Slavs. The Bulgars, led by Asp ...

Skat (river)
The Skat ( bg, Скът, ; also transliterated ''Skǎt'' or ''Skut''; la, Scitus) is a river in the western Danubian Plain of northern Bulgaria and a right tributary of the Ogosta. The Skat takes its source from the Rechka area near the Veslets mountain in Vratsa Province, part of the western Fore-Balkan Mountains, north of the Manyashki Vrah peak. It goes round the Borovan hill from the west and runs through a shallow gorge near Ohoden. From that point on, it has low banks and mostly flows through plain terrain with a number of meanders. The Skat is 510 metres wide, with a sand-covered bed. Its valley is asymmetrical, as the right bank is normally steeper than the left one. Before the construction of the atomic power station in Kozlodui the Skat flew into Danube directly. Then the Ogosta's course has been altered to free space for the atomic station separate canals and now the smaller Skat flows into the Ogosta at Saraevo, west of Oryahovo. The Skat is 140 kilometres long and h ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
